intro story D-Flow FM

 

D-Flow Flexible Mesh

D-Flow Flexible Mesh (D-Flow FM) is the new software engine for hydrodynamical simulations on unstructured grids in 1D-2D-3D. Together with the familiar curvilinear meshes from Delft3D 4, the unstructured grid can consist of triangles, pentagons (etc.) and 1D channel networks, all in one single mesh. It combines proven technology from the hydrodynamic engines of Delft3D 4 and SOBEK 2 and adds flexible administration, resulting in:

  • Easier 1D-2D-3D model coupling, intuitive setup of boundary conditions and meteorological forcings (amongst others).
  • More flexible 2D gridding in delta regions, river junctions, harbours, intertidal flats and more.
  • High performance by smart use of multicore architectures, and grid computing clusters.
An overview of the current developments can be found here.
 
The D-Flow FM - team would be delighted if you would participate in discussions on the generation of meshes, the specification of boundary conditions, the running of computations, and all kinds of other relevant topics. Feel free to share your smart questions and/or brilliant solutions!

Two questions about Delft3D GUI

Two questions about Delft3D GUI

Youngling Posts: 1 Join Date: 3/6/12 Recent Posts
Hello all,

I am a new user of Delft3D. I want to clarify some basic stuff about the software.

I am working on my master thesis in TUD using this software. My task is to improve some numerical methods. So I am dealing with the basic .f90 files and things like visualization and GUI are not so important to me.

About my OS system, I am working on Linux 32bit and I could also use s MS Windows if necessary.

Below come my questions.

(1) Using the software without GUI
Following the presentation by Fedor Baart, I finish compiling the source code(v5.00.00.1234) which I obtained by svn. And I run an example calculation using deltares_hydro.tcl config_flow2d3d.ini. But how can I use the command like deltares_hydro.tcl in Linux console to play with the software? Where is the related manual for these commands? I downloaded the Delft3D-FLOW_User_Manual.pdf but it is based on GUI. And I don't think GUI is indespensable in terms of my application purpose.

(2) Installation of the pre-complied GUI
Where is the FLEXnet license manager? After I have installed D3D together with its tutorial, /opt/delft3d/intel/flexlm/ doesn't appear. That meas FLEXnet license manager is not installed. I guess it is related to the DS license manager metioned on the webpage. Does DS license manager refer to Delft Hydraulics Softwaere license manager? Where can I download it?

Although the license manager is not settled, I am lucky enough to be able to run delft3d-menu in my terminal. I am now reading the manual and learning the GUI usage. But will there be any potential risk of running without license?

Best regards
Hanzhi

RE: Two questions about Delft3D GUI

I am also new and having the same trouble with flexlm not exsisting. Was this problem ever resolved?

Also -- Why is the aksusbd file a .deb and not an .rpm?

Hi Hanzhi -
You don't need the license or FLEXnet license manager for running standalone.


Hi Duncan -
I'm not sure.. from what I understand is that they are very similar arcane formats. But the .deb files are more universal than .rpm's. Rpm's are mainly for redhat linux.
